MAGHINEIRY' FORCONTINUOUSLY CUTTING COAL.

SPECIFICATIFON forming part of LettersPatentNo. 753,092, dated. February223, 1904. Application ledISeptemher 30, 1902. Serial No. 125,430. (Nomodel.)

of production; and with this object in view the invention consists inthe machinery hereinafter described, the particular points of novelty inwhich are afterward specifically suitable motor,the eccentrics will drawthe claimed. l

In the accompanying/drawings, in 'which I have illustrated' machineryconstructed in accordance with my invention, Figure l represents in planview machinery in position for operation. Fig. 2 represents in elevationthat portion of the same contained in the forward part of the tunnel inwhich the driving mechanism is located. Fig. 3 represents in planviewmachinery in which the rope carrying the cutting-tools is arrangedfor continuous operation in one direction. Fig. 4 represents inelevation the means for governing the tension of the rope carrying thecutters and feeding the cutters into the cuts as they progress.

Like letters indicate the same parts where they are shown in more thanone 'dgure of the drawings.

Referring to the drawings by letters, a, indicates a rope or cablecarrying cutting-tools o. Posts are temporarily erected in the tunnels,as at c c', consisting of blocks g g', Fig. 2, rigidly held against thetop and bottom of the tunnel 3 by right-and-left screw g2, and the ropeis passed over guide-pulleys t It', mounted on the blocks gand underguidepulleys on the blocks g', one of which is shown in dotted lines inFig. Q- at a', and around pulleys y' j', making an endless belt of thecutterrope passing across the breast at two levels, one in the plane ofthe top of pulleys t fr and the other in the plane of the bottom of thepulleys i.

on opposite sides of the pulley and set diametrically opposite to eachother on the shaft. To the strap of eccentric e is attached a cable 22,which passes over a guide-pulley 7c, mounted on a temporary post Z, andis attached to.

the shaft of pulley j', While a cable 21, attached to the strap ofeccentric e2, passes around guidepulleys f f f and over guide-pulleyc,mount ed on a temporary post Z, and is attached to the shaft of pulleyj. Thev pulley f may be actuated in the direction of the arrow f3 inorder to keep the rope a taut and feed it and the cutters into the cutsas they progress.

When the driven pulley 0l is actuated by any pulleys y' j alternately,and as one of them is drawn in one direction the other moves in theopposite direction, thus reciprocating the cutter-rope a across thebreast and making two cuts at the same time, as indicated at m m in Fig.2. A

In the construction illustrated in Figs. 3 and 4 two cuts are made atthe same time, butinstead of reciprocating the rope it is movedcontinuously in the same direction. The rope a is of the sameconstruction as in Figs. 1 and 2, carries cutters and is carried arounda pulley cw at one side and a pulley @2 at the other side, thus formingan endless belt which passes over guide-pulleys fnn, mounted on topblocks 0 o of a temporary post and under guide-puh post, one of saidblocks and pulleys being shown at 02 and p3 of Fig. Li, one side of therope passing across the breast on the level of the top of pulleys n aand the other on the level of the bottom of pulleys 293,. making twocuts at once, as in the mechanism shown in Figs. 1 and 2. The pulley amismounted on a shaft p on a truck fil", which shaft also carries anotherpulley driven by means of a belt t t from any suitable motor, (notshowin) said belt being guided by pulleys a a'. The pulley 62" ismounted on a shaft p on a truck 7b2, carried on wheels 71,3", on whichtruck therel is a drum g, upon which may be wound a rope g by means of acrank g2, said rope q being secured to any suitable fixture, (notshown,) so that by winding up the rope on the drum during the operationthe endless-belt rope a may IOO be governed as to tension and fed intothe cuts as they progress. In this construction the rope a movescontinuously in the same direction.

The operation ofthe machinery will be readily understood from theforegoing, and as the cuts progress and bring the front or cuttingportions of the cutting-rope too near t'o the guide-pulleys thetemporary posts may be removed and placed farther back in the tunnels. l

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In machinery for cutting coal, the combination with temporary postsin the side tunnels and upper and lower guide-pulleys carried thereby,of pulleys in the rear of said guidepulleys, an endless belt of ropecarrying cutters, passing over the upper guide-pulleys and across thebreast on the level of the top of said upper pulleys, under the lowerguide-pulleys and across the breast on the level of the bottom of saidlower pulleys, and around the rear pulleys, and suitable driving andfeeding means whereby the cutter-rope makes two cuts across the breastat the same time, substantially as described.

2. In machinery for cutting coal, the combination with temporary postsin the side tunnels and upper and lower guide-pulleys carried thereby,of pulleys in the rear of said guidepulleys, and suitable driving andfeeding means whereby the cutter-rope is driven continuouslyin the samedirection and makes two cuts across the breast at the same time,substantially as described.

3. In machinery for cutting coal, the combination with temporary postsin the side tunnels, and upper and lower guide-pulleys carried thereby,of a truck in one tunnel, a shaft thereon, a pulley on said shaft, Vasecond truck in the other tunnel, a shaft thereon, a pulley on saidshaft an endless-beltrope passing across the breast at two levels, oversaid guide-pulleys and around the truck-pulleys, a driven pulley on theshaft on the rst-named truck, a drum on the second truck, and a ropewinding thereon and adapted to be secured at its end, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
